Energy and threshold characteristics of chemical lasers

Abstract
A comparative study has been made of the time sequencing and energy content of the HF laser transitions in the CH3I+N2F4 chemical laser with two different cavity configurations. In one case the cavity is made up of two mirrors, and in the other case of a mirror and a grating. The prime conclusion of this work is that in order to understand the threshold behavior and energy content of multitransition chemical lasers it is necessary to invoke some kind of wavelength‐selective cavity. Furthermore, it has been observed that the use of a grating can channel a large portion of the normal total emission (obtained when the cavity consists of two mirrors) into a single transition.
